User Interface Design ProcessGabriel Spitz

User-Interface design Steps/Goals

Understandwho are the users

and what do they do

Articulatehow will users work

in the future

Conceptualizethe user interface

and interaction

DesignAn aesthetically

pleasing and consistent interface

EvaluateIdeas,

concepts, designs

User Interface Design Method

User interviews &

contextual observations

Task scenarios and walkthrough

Participatory design, Usability

principles, Design patterns

Graphical screen design

Articulate

While I call out “Articulate” as a separate step, it is often integrated with the Conceptualized step

Design Think and Think Design We use images to stimulate and guide thinking and we

use thinking to guide the design

Understand – Objectives

Build an understanding of the design problem Identify the business problem that we intend to solve Describe the users; what are their characteristics, likes,

dislikes, goals and needs Describe how and where we expect users to use the

product/application

Understand– Methods

Meet with Product team and identify the design problem, scope, and goals of the product

Meet actual and/or virtual users to figure out who they are, what they do, how do they do it today and what are their key needs

Identify Perform a competitive analysis of similar products or solutions to identify trends and benchmark what is out there

Understand– Deliverables

users currently perform User Experience Map

UI Components

Conceptualize – Objective

Build a clear and shared vision of the product or application we want to build Depict how the user interface will appear to users Help ensure that key user tasks are accounted for-

generate additional use stories and modify the design Select and wireframe the most suitable design ( one that

meets most of the requirements)

Conceptualize – Deliverables

Establish an overall conceptual model and sketches of the solution – the overall pattern, interaction style, metaphors

Create Task Model to describe the interaction

Create Page-wireframes to describe the interface (dialogue) concept

Create and review Application-wireframe to tie the interaction and interface design together within the context of user intention

Add new use stories, if needed, to ensure effective and comprehensive design

Conceptualize – Deliverables

Task flow model Application level – Sketches and Wireframe describing

in detail; Navigation, structure of each interface component, and the expected interaction within the context of specific user intentions

Use Stories Table (Task Identification)

Low Resolution Wireframe

Wireframes

Design – Objective/Why

Create a compliant and aesthetically pleasing rendering of the application wireframes

Ensure clarity and simplicity at the user interface Help new users quickly master product usage by

adding guidance and instruction where needed

Design – Methods

Review research and conceptual design to understand goals, intent, and proposed design

Skin each wireframe component to comply with corporate guidelines

Identify and design special components required by the design – e.g., icons, special labels, highlight colors, etc.

Review the visuals with UX and Documentation

Design – Deliverables

Clear, aesthetic and pixel perfect visual design Implementation guidance and specific components

(such as icons) to support front end developers User guides, help documentation and training

Visual Design User Guidance

Visual design

Evaluate - Objective/Why

Provide constructive and actionable input to specific design questions/issues

Continuously verify proposed design solutions Ensure usability both at the micro and macro level

Evaluate - Methods/How

Utilizing a mix of evaluation methods including: User interviews Local and remote usability tests A/B testing compering design alternatives On-line surveys

Evaluate – Deliverables

Test results Proposed areas in need for improvements Rational and prioritization for proposed change
